When shipping hazardous materials, it is important to keep your container units compliant to prevent
spill accidents or injuries. Steel IBCs that are UN/DOT approved need to be kept compliant with the U.S.
Department of Transportation standards which require 30- and 60-month testing.
Both UN and DOT-approved units require 30-month testing that will include:
- Visual inspection looking for damage to units such as creases, dents, or stretching in the metal.
- Inspecting all parts to make sure functional and pressure testing the unit to ensure no leaks.
- Plus completing the test by etching the unit on the label plate of the unit with the current test date.
UN-approved units will also require a metal thickness test every 60 months from the manufacture date. It
will ensure the walls of the units are thick enough for the transport of regulated products. This test also will get etched on the label plate of the unit with the current test date.
Both the 30- and 60-month testing require a current test certificate that will list the container’s serial
number, testing performed, and the result of the testing for you to keep on file.
If your unit fails either or both testing processes, the unit should not be utilized for shipping of regulated
